Abstract

A plug-in hybrid accessory belt drive system comprising a vehicle engine accessory belt drive, the accessory belt drive comprising engine accessories, a motor/generator engaged with the accessory belt drive, the motor/generator for driving the accessory drive, a rechargeable electrical energy source connected to the motor/generator for driving the motor/generator on demand, the rechargeable electrical energy course connected to a vehicle electrical load, and the rechargeable electrical energy source connectable to a recharging energy source.

Claims

1. A plug-in hybrid accessory belt drive system comprising:

an internal combustion engine accessory belt drive, the accessory belt drive drivable by the internal combustion engine and further comprising engine accessories;

a motor/generator drivingly engaged with the accessory belt drive, the accessory belt drive drivable by the motor/generator;

a rechargeable electrical energy source connected to the motor/generator for powering the motor/generator on demand and which rechargeable electrical energy source is also rechargeable by the motor/generator;

the rechargeable electrical energy source connected to a vehicle electrical load; and

the rechargeable electrical energy source connectable to a recharging energy source.

2. The plug-in hybrid accessory belt drive system as in claim 1, wherein the rechargeable electrical energy source comprises a battery..

3. The plug-in hybrid accessory belt drive system as in claim 1 further comprising:

a clutch mechanically disposed in the accessory belt drive such that when the clutch is engaged the engine drives the accessory belt drive system; and

the clutch is not engaged when the motor/generator is driving the accessory belt drive system.

4. The plug-in hybrid accessory belt drive system as in claim 3, wherein when the clutch is engaged the generator does not provide power to recharge the rechargeable energy source.
